Drilling water-sensitive shale formations often leads to wellbore instability, resulting in drilling problems because of the clay's high-water affinity. To solve this problem, different nanoparticles (NPs), such as nanosilica, have been used formulate water-based muds with potassium chloride (KCl-WBM). Nevertheless, unmatched pore size pores when using nanosilica fails completely prevent swelling and dispersion. This study discusses effects KCl-WBM sodium dodecyl sulphate-treated...

Insufficient hole cleaning, cutting suspension, clay swelling, and filtrate invasion of the formation might result from inadequate drilling mud properties. For effective wellbore stability, water-based (WBM) rheology, lubricity, filtration, shale inhibition must be optimized controlled. WBMs react with clays cause time-dependent borehole issues, which is their principal drawback. Moreover, prolonged exposure destroys certain WBM components, resulting in minimal These indicate need for...

Enhanced oil recovery (EOR) is the process of residual production in tertiary stage. It requires injection external energy sources such as gases, chemicals, and thermal reservoirs. Chemical enhanced (CEOR) can boost significantly by improving microscopic displacement trapped pore spaces reservoir rock. Each type chemical flooding depends on different mechanisms to enhance recovery. Surfactant aims reduce interfacial tension, alter wettability rock more water wet, promote porous media. The...

Abstract The natural pressure in hydrocarbon reservoirs is only sufficient producing small amount of at the end depletion stage. Therefore, order to enhance or increase recovery, water other fluids are injected into formation extract from pore space. This common practice known as Improved Enhanced Oil Recovery (IOR EOR). Foam purposely used some EOR displacement processes control mobility ratio, hence improving volumetric sweep efficiency. efficiency a foam process depends largely on...

The wettability of subsurface carbonate reservoirs is a critical factor influencing the pore-scale displacement fluids. As such, plays key role in enhanced oil recovery and greenhouse gas geo-sequestration. Wettability affects interaction between crude oil–brine-rock system distribution fluids within pore spaces. Oil can thus be improved by altering rock surface wetting properties from an oil-wet state to water-wet state. adsorption cationic surfactants induce alteration improve water...
